DOOR CLOSING AND HOLDING DEVICE.

SPECIFICATION forming part Of Letters Patent N0. 698,939, dated April 29, 1902. Application filed April 4, 1901. Serial No. 54 361. (No model.)

To all whom it ntcty concern:

Be itknown that I, JOSEPH L. HAMEL, a citizen of the United States, residing at Grafton, in the county of WValsh and State ofNorth Dakota, have invented new and useful Improvements in Door Closing and Holding Devices, of which the following is a specification.

My invention relates to door closing and holding devices especially-designed for use with double-acting swinging doors; and its object isto provide simple, inexpensive, and effective means for closing doors or holding the same in open position.

The construction of the improvements will be fully described hereinafter in connection with the accompanying drawings, which form part of this specification, and its novel fea tures will be defined in the appended claim.

In the drawings, Figure 1 is an elevation of a door equipped with my improvement. Fig. 3 is a detail view, partly in elevation and partly in vertical section, showing features not seen in the other figures. Fig. 4 is a front elevation of the inclined track of the device. Fig. 5 is a detail sectional view of the casing with the plunger therein.

The reference-numeral 1 designates a metallic plate of approximately semicircular shape and adapted to be secured to the fioor against the door-frame 2 at the side to which the door 3 is hinged. This plate is provided with a vertical flange 4, extending around the curved edge of the plate, and the upper edge of said flange is beveled to form oppo- I sitely-disposed inclined planes 5 and 6.

The upper edge of the flange 4 constitutes a track, as will be further explained, and it is formed with a central notch 7 and end notches 8 and 9, as shown in Figs. 1, 2, and 4.

The upper surface of the plate 1 is formed with a socket 10 to receive a pintle 11, depending from a corner-plate 12, secured to the lower corner of the hinged side of the door 3 and having a vertically-extending se the shoulder 21, while its opposite end is at-- tached to the upper end of the casing 15.

The walls of the casing are formed with vertical slots 23 to permit the door to pass over the higher portions of the inclined track way.

It will be apparent that the grooved roller 19 is held in contact with the trackway by thetension of the spring 22 and that said roller is projected into the slots of the trackway to hold the door in either open or closed position.

I claim The combination with a swinging door adapted to move only in a horizontal plane and provided with a mortise at its lower edge; of a slotted casing within said mortise, a spring-pressed plunger within the casing, a roller carried by said plunger, a plate secured below the door, an oppositely-inclined trackway upon the plate having notches therein, a corner-plate secured to the door, and a pintle depending from said corner-plate and adapted to bear in a socket in the plate of the trackway, said trackway being adapted to gradually move the roller and plunger inward and compress their spring during the opening of the door.

In testimony whereof I affix my signature in presence of two witnesses.

JOSEPH L. HAMEL.
